Dog Walker Portsmouth: 17 Years of Continuous Search Ranking and What Foundation Durability Actually Looks Like
Built by Sean Mullins in 2009 as hand-coded HTML and CSS (logo, website, flyers, terms and conditions, SEO). Rebuilt by a third party in 2016. Still ranks #1 organic for dog walker Portsmouth in 2026, 17 years on. A case study in foundation durability and what survives across a generation of search algorithm changes.
The Challenge
In 2009, Nikki ran a small dog walking business in Portsmouth and needed an online presence. She came to Sean Mullins for the full set: a logo, a website, the supporting collateral (flyers, terms and conditions, basic operational documents), and the SEO work to get found by Portsmouth dog owners searching for a local walker.
The challenge was the search landscape of 2009. Local search was emerging but not yet dominant. The local pack as it exists today did not exist. Google rankings for queries like “dog walker Portsmouth” were a function of clean, structurally correct sites with genuine local relevance. There was no quick way to win the position; the only path was to build a foundation strong enough to rank for the head term and hold it.
In 2016, Nikki had the site rebuilt by a third party. SEO Strategy Ltd was not involved in the 2016 rebuild. What is notable, and what this case study documents, is that the 2009 foundation work was structurally durable enough that the site continued to rank through and after the rebuild, and continues to rank today, in 2026.
The Solution
The 2009 engagement was full-stack work for a sole-trader business at small budget. Five distinct deliverables.
LOGO DESIGN. A simple, recognisable logo for Dog Walker Portsmouth designed by Sean Mullins. The brand identity was kept clean and approachable, matching the customer-facing tone of a small local dog walking business.
WEBSITE BUILD. The site was built in 2009 as hand-coded HTML and CSS. No WordPress, no CMS, no plugins. The structure was deliberate: a clear home page with the head term in the title tag and H1, supporting pages for services, rates, contact, and the geographic service area, and contact information visible on every page. The decision to hand-code rather than use a CMS was a deliberate one for a low-budget local business: a fast, structurally clean site with no plugin bloat, no theme overhead, and no maintenance complexity Nikki could not handle herself.
SUPPORTING COLLATERAL. Flyers for door-to-door distribution and pinning in local pet shops. Customer-facing terms and conditions. Basic operational paperwork to support a regulated service handling other people’s dogs.
LOCAL SEO. The 2009 SEO work focused on the foundations that mattered for local discovery in that era: clean URL structure, keyword-anchored title tags and H1s, geographic relevance signalled clearly on every page, NAP consistency across the early local directories, descriptive image filenames and alt text. The Google Business Profile precursor (Google Places) was claimed and completed. Citation building across the local directories that mattered at the time.
THE 2016 REBUILD. In 2016, Nikki had the site rebuilt by a third party. SEO Strategy Ltd was not involved. The rebuild changed the visual design and the underlying technology stack. What the rebuild did not change was the brand identity, the URL structure for the head-term pages, the local-anchored content, or the citation history built up since 2009. The structural foundation that had been built to rank for the head term continued to do its job under the new technology stack.
What Made This Different
This case study is unusual because it documents foundation durability across a 17-year span and a third-party rebuild. Most SEO case studies cover six to twelve months and stop. This one covers a generation of search-engine algorithm changes, two major Google Core Web Vitals shifts, the rise of mobile-first indexing, the local pack as we know it, the helpful-content update, and now the AI Overview era. The site has ranked through all of them.
The case study is also unusual in being transparent about the limit of the engagement. Sean Mullins built the site in 2009; the 2016 rebuild was handled by a third party; Sean was not involved in the 2016 work. What the case study claims is that the structural foundation laid in 2009 was durable enough to survive a rebuild and keep ranking. What it does not claim is that Sean has been doing the SEO continuously for 17 years. That kind of honesty matters because the alternative framing (“our SEO is still working 17 years later”) would be misleading.
For Portsmouth-area businesses, the proof point that matters is the live SERP: searching “dog walker Portsmouth” returns the site as a top organic result, exactly as it has done continuously since 2009. That is the strongest possible evidence that the foundation work was correct: it is still in place and still doing its job.
The Results
Live on the SERP as of May 2026, verifiable by searching the head term on Google.
CONTINUOUS RANKING SINCE 2009. The Dog Walker Portsmouth website (thedogwalkerportsmouth.co.uk) has held a first-page ranking for “dog walker Portsmouth” continuously since the original 2009 launch. Seventeen years of sustained visibility for a competitive local commercial query.
RANKING SURVIVED THE 2016 REBUILD. The site was rebuilt by a third party in 2016 and rankings held through the rebuild and beyond. This is unusual: site rebuilds frequently cause measurable ranking drops because URL structures change, content is rewritten, internal linking is altered, and the citation history attached to specific URLs is disrupted. That the rebuild did not damage rankings is a reflection of the foundation work done in 2009: clean URL structure for the head-term page, geographic relevance signalled clearly enough that the new build inherited it, and a citation history at the domain level rather than fragile page-specific patterns.
NIKKI MAINTAINS THE TOP SPOT TODAY. The site continues to rank prominently for “dog walker Portsmouth” in 2026, more than 17 years after the original build. The relationship with Nikki has remained good throughout, even though SEO Strategy Ltd was not involved in the 2016 rebuild.
WHAT THIS CASE STUDY PROVES. SEO foundations done correctly in 2009 are durable enough to survive a rebuild seven years later and continue to rank seven years after that. The mechanism is not magic: it is structural cleanliness, geographic relevance, and citation history built at the domain level. Most local SEO does not last this long because most local SEO is built around tactics that depend on a specific platform, theme, or plugin. The 2009 work was built around the structural fundamentals that outlast any single CMS, theme, or rebuild.
Frequently Asked Questions
Did Sean Mullins do the 2016 rebuild?
No. The 2016 rebuild was handled by a third party. Sean Mullins built the original site in 2009 (logo, website, flyers, terms and conditions, SEO) and was not involved in the 2016 rebuild. What this case study documents is that the structural foundation laid in 2009 was durable enough to survive the rebuild and continue ranking. The relationship with Nikki has remained good throughout.
How can a 2009 site still rank 17 years later?
Three things compound. First, the site was structurally clean from the start: clear URL structure, keyword-anchored title tags and H1s, geographic relevance signalled clearly on every page. Second, the local citation history was built at the domain level: NAP consistency across the local directories that mattered in 2009, Google Business Profile precursor (Google Places) claimed and completed. Third, the 2016 rebuild did not break the structural decisions made in 2009 (URL structure for head-term pages retained, brand identity unchanged, geographic anchoring preserved). The combination of original cleanliness plus rebuild discipline produced durability.
Is hand-coded HTML still a sensible approach for local businesses in 2026?
For most local businesses, no. WordPress with a well-built theme, clean schema markup, and proper local SEO setup is more practical because it gives the owner the ability to make updates without developer involvement. The reason hand-coded HTML worked in 2009 for Dog Walker Portsmouth was specific to the era and the business: low budget, simple service offering, owner who did not need ongoing self-service publishing, and a search algorithm where structural cleanliness mattered more than any other signal. Today, a comparable build would more likely be a clean WordPress installation with a custom or carefully chosen theme and proper schema implementation.
